Реферат: Multi-wall carbon nanotubes (MWCNTs) have been widely regarded as an attractive candidate to be used as fillers in composite materials due to their unique mechanical properties, large surface area, high electrical and thermal conductivity, and chemical stability. The development of new composite materials based on widely used polymers and MWCNTs is one of the promising fields of modern material science. The addition of a small amount of the MWCNT to the composite materials based on polyolefins provides significant improvement of their mechanical and electrical properties. The addition of the third component such as nanosized metal particles to the composite material at the preparation stage potentially allows the adjustment of the electrical properties of the material by varying not only the dielectric properties of MWCNT, but also magnetic properties of metals. Moreover, the resulting "triple" composite materials are able to acquire completely new properties, for instance, electromagnetic shielding. In this work, a new approach for the synthesis of these materials based on in situ polymerization of ethylene using Ti-containing catalysts previously adsorbed on the surface of Co/MWCNTs has been developed and utilized. Co/MWCNT-PE composite materials with different ratios of the components Co:MWCNT:PE have been obtained. The study of electromagnetic response has shown that the Co/MWCNT-PE composites can be used as a promising material for the development of broadband shielding to be used for effective reflecting the electromagnetic radiation (10-16 GHz).
